Quart Web 应用程序上的 asyncio Discord bot 会话超时

Question

我正在尝试在 Quart 上实现与 Web 应用运行的不和谐机器人连接。我尝试使用发布的其中一种解决方案，它可以工作一段时间，但大约 24 小时后应用程序中断返回 asyncio.exceptions.TimeoutError

     data = await state.http.send_message(channel.id, content, tts=tts, embed=embed,
   File "/path/to/my/venv/lib/python3.9/site-packages/discord/http.py", line 185, in request
     async with self.__session.request(method, url, **kwargs) as r:
   File "/path/to/my/venv/lib/python3.9/site-packages/aiohttp/client.py", line 1117, in __aenter__
     self._resp = await self._coro
   File "/path/to/my/venv/lib/python3.9/site-packages/aiohttp/client.py", line 619, in _request
     break
   File "/path/to/my/venv/lib/python3.9/site-packages/aiohttp/helpers.py", line 656, in __exit__
     raise asyncio.TimeoutError from None
 asyncio.exceptions.TimeoutError

相关代码：

import discord
import asyncio
from quart import Quart, request, Response

app = Quart(__name__)
client = discord.Client()

@app.before_serving
async def before_serving():
    loop = asyncio.get_event_loop()
    await client.login(os.getenv('TOKEN'))
    loop.create_task(client.connect())

@app.route('/webhook', methods=['POST'])
async def webhook():
    ...
    await channel.send(content, embed=embed)
    ...

如何让客户端循环保持一天以上？有没有办法防止客户端会话断开连接，或者我应该定期重新连接它？

我咳嗽 asyncio.TimeoutError 并设法重新启动会话：

async def discord_post(channel, message, embed):
    try:
        await channel.send(message, embed=embed)
    except asyncio.TimeoutError:
        await connect_client()
        await channel.send(message, embed=embed)
    
@app.before_serving
async def connect_client():
    loop = asyncio.get_event_loop()
    await client.login(os.getenv('DISCORD_TOKEN'))
    loop.create_task(client.connect())

@app.route('/webhook', methods=['POST'])
async def webhook():
    ...
    await discord_post(channel, text, embed)
    ...

但是处理重启需要将近 300 秒，之后所有请求都会被立即处理并且 nginx 一直返回 499，即使代码现在正确执行，但我想这完全是另一个问题
